Observing Broadband Tsunamis in Deep Water Via Distributed Acoustic Sensing

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Tsunamis have been detected as strain variations in optical fibers of submarine cables through distributed acoustic sensing (DAS). However, the usefulness of strain variations during tsunamis for early warning remains unclear. Here, we compare fiber strains and sea‐level changes for both infragravity waves in ambient noise and tsunamis ...

Regional‐to‐Global Tectonic and Trench‐Morphology Effects of Oceanic Plateau Subduction

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Regional geodynamic modeling has shown that oceanic plateau subduction can modify the slab behavior. However, few studies have explored these interactions beyond 100 Myr in 3‐D spherical models. Using 3‐D spherical mantle convection models with self‐consistent plate‐like behavior, we investigate how the geometry and rheological properties of ...

Characterizing the Unique Chemical Imprint of On‐Axis, Lower‐Temperature Hydrothermal Flow to the Deep Ocean (Southern East Pacific Rise, 16.5°–18.0°S)

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract In addition to high‐temperature vents, lower‐temperature flow (LTF) (<300°C) is abundant along mid‐ocean ridges and contributes globally‐important fluxes of heat and water along with largely‐unconstrained geochemical influences on the ocean. We examined the impact of on‐axis LTF on the chemical composition of the overlying water column (<40 m ...

Evaluation of Catch Performance and Environmental Impact of Technical Gear Modifications for a More Sustainable Scallop Dredging Fishery

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Catch and environmental performance of modified scallop dredge designs were assessed. Skid belly bags increased scallop catch by 14%–19% and reduced gear wear. N‐Virodredge reduced catch of scallop juveniles and sorting time. Gear footprint on the seabed was reduced by 50% for skid belly bags. N‐Virodredge cut fuel use by 30%, reducing carbon emissions

Assessing Conflict Potential Between Birds and Small‐Scale Fisheries in Lake Titicaca

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 4, April 2026.
ABSTRACT Globally, fisheries bycatch constitutes a threat to aquatic birds. However, while the threat is global, the threat from bycatch in inland fisheries, and from artisanal or small‐scale fishing, is particularly understudied. Here, we present the first attempt to map the vulnerability of birds to fisheries bycatch, and the conflict potential ...
